@Halfwaythere,
Apologize for what?
According to you, HE misled you in that you thought you two were going to start dating. You were so sure of it.
But reality is that you two were just friends, fooling around with talk, but when the "real" one came back, he dropped all interest like a hot rock.
Like I said before, be sure the guy is FREE of all hangups from the past and other baggage (drugs, alcohol, bad grades, legal problems, etc.) BEFORE you start sweet talking.
Good luck and now - carry on!!
